Pangea is by far the most famous and the most recent supercontinent. Spanning from the Pennsylvanian epoch, the second one in the Carboniferous period to the early Jurassic period, This supercontinent allowed animals and plants to spread and roam all over the land. It has been proven that fossils around this time were pretty much global and not restricted to specific continents. It formed with the closure of the Rheic Ocean and broke apart with the opening of the Atlantic Ocean.

Before Pangea, there were two continents called Laurasia and Gondwana (sometimes called Gondwanaland), and after Pangea broke apart, there were two continents too, also called well... Laurasia and Gondwana. The early Laurasia and Gondwana are sometimes called Paleolaurasia and Paleogondwana to prevent mixup of the names.

The name of Pangea originated from Greek where Pan means all and Gaia means earth. The name of Laurasia is made from concatenating the names of the Laurentia Craton (Today's North America) and Asia. Gondwana means "Land of Gonds (a tribe in India)".

Paleontology is the study of geological events before (sometimes including) the Holocene Epoch which we currently live in. It includes the study of ancient organisms, extinction events, and changes to the Earth.

Rodinia is a relatively famous supercontinent that existed towards the end of the Proterozoic Eon. Nevertheless, many people don't know it. It existed from the Stenian period to right before the Cryogenian period encompassing nearly all of the Tonian period.

It was almost exactly on the opposite side of where Pangea formed. It turned inside out during the Cryogenian period to become Pannotia, leaving out exposed rocks that sucked up carbon dioxide, thus causing a snowball earth. Pannotia somehow still didn't make it into the Phanerozoic Eon.

Rodinia wasn't by itself unlike other supercontinents. It had a continent to the west of it as its companion. Made of parts of South America and Africa, this continent was called Congo. While Rodinia turned itself inside out, Congo got caught in between the two halves, completing Pannotia.

Comprising of the Paleozoic, Mesozoic and Cenozoic eras, this eon spans 541 million years from the Cambrian Explosion to today.

During the Paleozoic era, complex life started to appear. It took 100 million years for the aquatic plants and animals to migrate to land. Then, another 130 million years later, giant bugs started to appear. 60 million years later, entire coalfields from the Carboniferous Rainforest Collapse Event were set on fire by volcanic activity, causing the Permian-Triassic extinction. The Mesozoic era had begun.

20 million years later, dinosaurs started to appear. They died altogether during the Cretaceous-Paleogene extinction 66 million years ago beginning the Cenozoic era. The mammals started to dominate land. 60 million years later, the Mediterranean Sea drained up, but quickly refilled due to closure and reopening of the Strait of Gibraltar. 6 million years later, humans finally appeared, ending the story of earth's life as we knew it.

A very short lived supercontinent. It formed in the beginning of the Ediacaran period of the Proterozoic Eon, but broke apart as Laurentia rifted away from the rest of the supercontinent. It broke apart even before the Phanerozoic Eon and the Cambrian period. Not so well-known although is one of the only interesting things that happened during the Ediacaran period.
